traffic switching with two loadbalancers fails

[ramirantala]

We have senza definition that defines two loadbalancers.

We use two loadbalancers since we need to provide two urls from different domains with different certificates for time being. Deployment works fine, no problem there, but when switching traffic, with latest senza, traffic switching fails.

We get error like this:

Validation Error: Stack:arn:aws:cloudformation:eu-central-1:our-account:stack/m-prod-201612150640/61603400-c291-11e6-9677-50a68ad4f2c6 is in UPDATE_IN_PROGRESS state and can not be updated.

Stack updates fail with error:

Tried to delete resource record set [name='our-url-is-here.', type='A', set-identifier='m-prod-201612291008'] but the values provided do not match the current values

However, it works with senza version 2.0.109

@ramirantala can you have a look at #466

That PR should address the underlying problem and fix it.
